From Virtual to Real, Is it Possible ?
If it had been pure science, 'Energy to Mass' would have sounded appropriate. As the movie introduced a technique which could possibly create matter out of thin air (Well, that's what you mean when you say "From Virtual to Real World"), the director thought it better to show a hologram. It was claimed in the movie that with this technology it became possible to feel the holograms. Wait ! This isn't science fiction. Volumetric Displays have been around for some time. Some of those displays create voxels of plasma (volumetric pixels in 3D space) in air through pulsed laser. So, you can literally 'feel' the hologram as the laser burns through your hand. Besides that, another holographic system will make you feel the hologram by using acoustic pressure waves within the projection space.
Okay, Enough with holograms. But in order to create actual matter out of nothing, you need to make sure you have the $10 billion Large Hadron Collider.
The Evolutionary Artificial Intelligence
The movie demonstrated Ra.One's ability to learn and develop its neural schema, knowledge base, and its ability to program itself. Ra.One also had the ability to control the wearer of the gaming suit. Assuming that the gaming suit is populated with sensors and circuits only, this controlling feat of Ra.One is purely bogus. But, the learning ability of Ra.One has already replicated by many computer programs and even some robots like ASIMO. Evolutionary AI, in its strictest sense means a parent program creating daughter programs, each with small random changes, and choosing the daughter program which completes the task better than others as well as the parent, to be the next parent program.
Shape-Shifting and Self-Repairing Ability
The shape shifting ability of both the antagonist as well as the protagonist as portrayed in the movie resembles Terminator-2's villain's ability. While Ra.One is a full-fledged shape shifter, G.One isn't and can only get back to his original form when disfigured. US researchers are developing swarm robots that use electromagnetic fields to form different shapes and formations.
Thus the shape-shifting shown in Ra.One doesn't seem very far-fetched, and probably closer to reality with the dawn of swarm robotics.
However, A robot being able to repair itself without human intervention doesn't even seem possible with swarm robotics because when the modules, or individual pieces forming the robot get destroyed, they aren't going to just pop-up as new.
Conclusion
It is obvious in Indian sci-fi's that their science doesn't have a proper basis. If compared with Rajnikanth's Enthiran (ROBOT), Ra.One is certainly more fiction packed, where Robot had less of sci-fi and more of how robots could be domesticated. So on the whole Ra.One seems a "haphazard medley of Iron Man, Terminator, Matrix, Superman, with age-old acts of levitation that we've seen over and over".
